I bought this in order to get into natural carbonation and pressure fermentation, and I just about love the thing. Obviously, it's easy to use (set a regular to target pressure and adjust the valve til it just barely vents), and it seems relatively sensitive, which is great. The only caveat: mine came with a fitting that had no plumber's tape, which I applied, and the fittings were loose enough that I hemorrhaged CO2 until I soap-tested the thing and tightened it. Also, I looked into making one myself, and the price is very similar, so it's worth mentioning that this thing is a solid deal. In summary: totally get this if you need it (you do or you don't), but be prepared to tighten it up - when in doubt, check each connection with soapy water while under moderate pressure
